How do I view panoramic pictures on iPhone

HI, I received a fb pic in panoramic mode, and it has inspired me to use it on my iPhone 6.

However, on Facebook it is really easy to view by tilting the phone or using your finger. When I try and view my panoramic pictures on the phone they are just a squeezed picture. Apart from uploading them to Facebook to view them, is there any way or is there an app which would allow me to view my pictures like the FB way.?
